Grafting of ZrO2 powder and ZrO2 membrane by fluoroalkylsilanes

Grafting of ZrO2 powder and ZrO2 membrane by fluoroalkylsilanes. Krajewski, Sebastian R.; Kujawski, Wojciech; Dijoux, Frederic; Picard, Celine; Larbot, Andre (Faculty of Chemistry, Nicolaus Copernicus University, Torun 87-100, Pol.). Colloids and Surfaces, A: Physicochemical and Engineering Aspects, 243(1-3), 43-47 (English) 2004 Elsevier. CODEN: CPEAEH. ISSN: 0927-7757. DOCUMENT TYPE: Journal CA Section: 38 (Plastics Fabrication and Uses) The hydrophobic properties of zirconia membrane have been obtained by grafting fluoroalkylsilane on the surface of the ceramic material. Several different grafting expts. were conducted using zirconia powders to det. the optimal conditions of grafting. The detd. optimal conditions were then applied for the prepn. of the hydrophobic membranes. The grafting parameters such as the ratio of the amt. of fluoroalkylsilane compd. to zirconia mass in the grafting soln., and time and the temp. of grafting were studied. Thermogravimetric anal. (TGA) was used as a technique for the characterization of the grafted powders. The TGA scans allowed to det. 101947-16-4 and 1314-23-4 are cas registry numbers of chemicals which are used as reagents here. the grafting efficiency. The liq. entry pressure (LEP) and the water flux through the grafted membranes were also measured. The detd. LEP and water fluxes proved that grafting process was very efficient. Contact angle measurements were addnl. done to prove the hydrophobic character of the membrane surface. The hydrophilic character of ZrO2 membrane can be changed into a hydrophobic one by grafting 1H,1H,2H,2H-perfluorodecyltriethoxysilane on the surface of the membrane. The performed expts. allowed to det. the optimal conditions of grafting process. Obtained membranes show good hydrophobic character. .
